Out of curiosity I tested the patched Boing under Kickstart 27.3. I copied it to a blank bootable disk, along with mathtrans.library from a Workbench 1.0 disk (since the demo needs that). The emulated system locked up on running the demo. I didn't investigate further as to why.

r.cade: Yes, you are right. That was more me guessing why they wanted 1.0 than what they actually said. It's probably more to do with saying 'This is what it could do when it first came out', I guess. If the screen shows a later version it kind of spoils it a bit.

stevsurv: Could you point me to a download of that?

I have 2 adf's with file dates of 25-nov-85 and 22-aug-85 on the juggler demos. The byte sizes of the files and the disk are different on each adf - No files are crunched or packed. There are other demos varying in size on each adf as well.

Only problem is am legally unsure of uploading to the zone as each adf are both labeled - "Workbench Demos"

It's okay to upload those. I have uploaded Workbench Demos myself in the past.

I believe those I uploaded may have been programmed for use by Amiga dealers running them on their display machines.

Thanks for that! So it seems there are at least three distinct versions of the original/early Boing demo:
- The 1.0-compatible one.
- The later requires-1.1 one.
- The still-later one where you can adjust the speed of the ball, not just start/stop it.

The earliest version gives a clue as to the reason why the original OpenLibrary() function was renamed OldOpenLibrary(), and a new OpenLibrary() call introduced with Kickstart 1.1.

In the earliest version, the C compiler startup code doesn't put the minimum required library version in D0 before calling [Old]OpenLibrary() to open dos.library.

I hadn't seen the Mandril demo before. The original version is on wb_1.0_demos-22aug85.adf. The version on wbdemos-25-nov-85.adf has been patched by someone to work with fast memory, so that will no longer run under Kickstart 1.0.

To run the original version, run NoFastMem first. Also note that it must be run from Workbench, not CLI.
